IMPROVEMENT IN WATER-WHEELS.

The Schedule referred to in these Letters Patent and making pari of the same.

To whom it may concern Be it known that l, McKnNnnEE A.kBnoons, of La lortc, in -Ihe county of La Porte, and State of Indiana, have invented a. new and useful Improvement in Turbine Water-Wheels; and I do declare that the following is a true and accurate description thereof', reference heilig had to the accompanying drawings, and tothe letters of reference marked thereon, and being a part of this spcciiication.

Figure 1 is a perspective ofthe scroll and gate, showing the case in section, with the wheel removed.

Figure 2 is an elevation of the wheel.

Likeletters refer to like parts in each figure.

The nature of this -invention relates to an improved construction of turbine water-wheels, and consists in the peculiar construction of a doulle case andr scroll, provided with independent gates, so 'arranged that water may be delivered to either the upper or lower buckets of a double turbine wheel, orto both, as may lm'dcsired.A The purpose I have in this form ot' construction is, that with a diminished'amount of labor to perform, a less amount ot' water may be fed to the wheel, and, lling the issues of one ot' its sets ot buckets, will compel thewheel to revolve with undiminished speed. i

In the drawings- A represents my wheelfspindlc, stepped in `the usual manner, and4 carrying a wheel having an upwardfdischarging set of buckets, B, and a downward-discharging series of buckets, B'.

The base of eachv series ofgbuckets is secured to` a central disk', 0,'eucircling the hub ot' the wheel.

The disk C serves as a diaphragm, to separate the upper trom thelower series ot' buckets.

The wheel rotates within the case D, the water Leing delivered to it through the scroll f rlhe scroll4 and case are divided into au upper and lower chamber, by a horizontal diaphragm, F, in the case, aud surrounds the disk of the wheel, forming a joint tight enough to preclude the passage cf water from one chamber to the other.

-The mouth of the upper chamber of the scroll is provided with a gate, G, operated by a rack and pinion, or other suitable means for regulating the admission of water to that chamber and the upper series ot' buckets in the wheel, while the lower chamber is provided with 'a similar gate, G', operated finv like manner, for the same purpose, with reference to the lower series of buckets.

It will be noticed that the gates are operated independently of each other, so that water may be ad-i mitted to act upon either'series of buckets, or both, as circumstances may require. I

When the full power ofthe wheel is required, both gates are opened. When less power is required, one

of the. gates is closed, `and water admitted to only one series ot' the buckets, whose issues, being'flled with Athe dischargingwater, will compel thewheel to rota-te with au undiminished speed.

What I claim as my invention, and desire to secure by Let-ters Patent, isl 1. A water-wheel having a series of upward-discharging buckets, B, and a series ot' dowlpvarddis charging buckets, B', separated by a disk, C, rotating within a case, D, and' so arranged thatthe ,water may act upon either or both series ot' buckets, substantially as and for the purpose set forth.V

2. In combination with a water-wheel, construct-ed as herein described, the case D and scrollE, divided int-'o separate chambers by tbedizmhragm F, and pro-- vided with independent gates, G G', the whole arranged and operating in the manner and for the purpose speeiied.
